Inquiry: Does the GNI per capita of a country affect the average life expectancy? Hypothesis: I believe there will be a direct correlation between the GDP and average life expectancy, however I think things such as recession, and geographic location may also have an effect on the results. Countries I've decided to analyze: Australia, Austria, Cameroon, Canada, Chile, Denmark, Ethiopia, Luxembourg, Mexico, Netherlands, Niger, Peru, Samoa, Serbia, Singapore, South Africa, Spain, Sudan, Sweden, Thailand, Togo, Tonga, Turkey, Uganda, Ukraine, United Kingdom, USA, Zambia Years I've decided to analyze: 2005, 2006, 2007, 2008 Using these years will show the bust and boom of the economy to help me factor in recession.

Other thoughts: - Do GDP and literacy rates correlate? - Do teen pregnancy rates and literacy rates affect eachother? - Is there a correlation between - Do teenpregnancy and GDP correspond?
Basic Graphs:
2005 Mean Age= 69.07 years Mean GNI= $17596.67 Median Age= 73 years Median GNI= $4850 r= 0.69087647157058
2007 Mean Age= 69.82 years Mean GNI= $21130.74 Median Age= 73 years Median GNI= $7380 r= 0.71004719740019
2006 Mean Age= 69.48 years Mean GNI= $18773.70 Median Age= 73 years Median GNI= $5480 r= 0.70231054862859
2008Mean Age= 70.14 years
Mean GNI= $20816.07
Median Age= 73.5 yearsMedian GNI= $7360r= 0.71876911800637
Note that all of the above graphs have a logarithmic shape and the trend over all four years is the same.
Edited Graphs:
I took the Log of both sets of data and graphed it, note how the correlation is linear.
r =0.83787083071754
This indicates that there is a strong positive correlation
Hidden Variables:
Race
Climate
Culture
Lifestyle
Cost of Living
Recession
War
Disease
Political Instability
Conclusion:
My Hypothesis was Correct! The correlation was a strong positive one, just like I predicted. However I did not expect a log function. Overall I find my results to be very accurate, thorough and insightful.
